Description
Revision ID Revision ID.
GPIO0 Output
Value
D_GPIO0
Output Value
Local GPIO Output Value. This value is output on the GPIO pin when the GPIO function
is enabled, the local GPIO direction is set to output, and remote GPIO control is disabled.
0: Output LOW (default).
1: Output HIGH.
If PORT1_SEL is set, this register controls the D_GPIO0 pin.
GPIO0
Determines operating mode for the GPIO pin:
ModeD_GPIO0 xx0: TRI-STATE™.
Mode
001: GPIO mode, output.
011: GPIO mode, input.
101: Remote-hold mode. The GPIO pin will be an output, and the value is received from
the remote Deserializer. In remote-hold mode, data is maintained on link loss.
111: Remote-default mode. The GPIO pin will be an output, and the value is received
from the remote Deserializer. In remote-default mode, GPIO's Output Value bit is output
on link loss.
If PORT1_SEL is set, this register controls the D_GPIO0 pin.
